Description

Condensation adulteration prevention implement for grinding machine

The present invention relates to a condensation preventing structure of a grinding apparatus, and more particularly, to a condensation preventing structure of a new basket mill that can prevent water from mixing by condensation when grinding a grinding material such as printing ink or paint. It is about.

Paint is composed of paint pigments, resins and solvents of unique colors. Basket mills are used to grind paint, and basket mills are often used to grind printer inks as well as paint inks. . Such a basket mill is intended to improve the quality of paint or ink by grinding paint or printer ink into finer particles.

The basket mill is configured to include a cylindrical grinding barrel and a rotation shaft which is embedded in the grinding barrel in an upright direction and provided with a grinding blade at a lower end side thereof to be rotationally driven by a motor. At this time, the base through which the lower portion of the rotation shaft passes is embedded in the grinding barrel, and the shaft support member rotatably supporting the upper portion of the rotation shaft is exposed to the upper portion of the grinding barrel, while the upper and lower ends of the shaft support member and the base are respectively. A plurality of supported cooling tubes are installed in the vertical direction.

Accordingly, as the rotation shaft is rotated by inserting a material for grinding, such as paint or printing ink, into the grinding vessel, the grinding blade can be ground into small particles by the grinding blade. At this time, heat is generated during the grinding operation, and the grinding material may be cured by the heat, and thus the physical properties thereof may be changed, and in some cases, the material may be hardened. Thus, the cooling water is supplied to the cooling tube 18 to cool.

At this time, the cooling tube is composed of an inner tube which is connected to the cooling water supply pipe and into which the coolant flows, and an outer body covering the outer circumferential surface of the inner tube, and the space between the outer body and the inner tube is made of a vacuum chamber and built in the grinding vessel. Condensation is prevented by minimizing the contact rate of air to the cooled cooling tube. That is, the inside of the cooling tube is made into a vacuum chamber area to prevent condensation due to contact with air.

By the way, although the portion introduced into the grinding vessel in the cooling vessel can form a vacuum chamber as described above to prevent condensation, a portion of the upper side of the cooling vessel is exposed to the outside of the grinding vessel to mediate the connector to the upper end of the cooling vessel. The cooling water supply pipe must be connected. As such, condensation due to contact with air occurs on the outer surface of the cooling pipe and the cooling water supply pipe, and moisture generated by the condensation penetrates into the grinding vessel. It can cause serious problems that result in the failure of grinding materials such as.

If the paint or the ink itself is water-based, it should not be a problem, but it is mostly oily in the ink or paint, and water and oil will be generated as soon as water formed by condensation enters the oil-based grinding material (for example, oil ink). If they do not mix, the water will float on the oil, and when the product is released in this state, the water will not be painted but will be immediately defective. For this reason, the water produced by condensation should not be mixed with the grinding material.

Therefore, there is an urgent need for a means for preventing water from mixing due to condensation when grinding printing ink, paint, and the like.

An object of the present invention was developed to solve the problems described above, the object of the present invention is to prevent the mixing of water by condensation when grinding the grinding material such as printing ink or paint, thereby grinding It is to provide a new condensation prevention structure of the basket mill that can prevent the defective product.

According to the present invention for solving the above problems, the cooling tube of the structure in which the outer body 16 is coupled to the outer circumferential surface position of the inner tube body 14 into which the coolant is introduced, with the outer body 16 coupled thereto. A connector 20 coupled to an upper end of the outer body 16 and a cooling water supply pipe for supplying cooling water into the inner tube body 14, and at a lower position of the connector 20; Moisture due to condensation formed at the connection portion between the cooling water supply pipe and the cooling pipe 18, which is mounted around the outer body 16 of the cooling pipe 18 and connected to each other via the connector 20 so as to be disposed. The condensation mixing prevention structure of the grinding apparatus, characterized in that it comprises a bowl 30 for collecting it is provided.

According to the present invention, when moisture is generated due to condensation due to contact with air on the outer surface of the cooling pipe body exposed to the upper surface of the grinding vessel of the grinding device and the cooling water supply pipe, the water is taken down from the outer surface of the cooling pipe body. Moisture is collected in the bowl provided on the outer circumferential surface of the exterior body, so that no penetrating into the grinding vessel occurs. Therefore, the grinding material such as print ink or paint is prevented from becoming defective due to moisture penetration. . As moisture generated by condensation goes down through the cooling tube and is never blocked by the bowl, which is the main part of the present invention, it is never penetrated into the grinding material, thereby eliminating the serious problem of expensive ink or paint becoming defective due to moisture infiltration. You can do it.

In addition, according to another embodiment of the present invention, as a structure including a sealing member for sealing the connection portion of the connector and the cooling tube and the connection portion of the connector and the cooling water supply pipe at all to block the air contact, the condensation caused by the air contact Since there is no sealing member at all, it has the advantage of more effectively blocking the phenomenon of moisture due to condensation penetrating the grinding material.
